Extract from the Declaration of Independence; Washington's farewell address; Lincoln's Gettysburg speech, and second inaugural address
Least-square reductions of observations taken, at equal intervals, of the independent variable that follow approximately a parabolic or linear law frequently occur in physics and engineering practice. Makeshift devices are often employed to avoid the arithmetical work of determining the constants of curves which properly represent such data. In this paper the ordinary least-square formulæ are subjected to mathematical treatment, and rigorous solutions are evolved which require an ultimate...

Contains the results of an investigation during which the Brinell hardness was determined for five steels varying in carbon content from 0.07 to 1.12% after heat treatment arranged to produce wide variations in grain size. Upon heating for 6-hour periods no very appreciable increase in grain size occurs until the Ac transformation has occurred. The change in grain size often appears to be a very abrupt one, taking place within a narrow range of temperature. Two methods were used for obtaining...

Describes the application of photography to the detection of small changes in a complicated group of objects. A photograph is taken of the group before and after a change is suspected to have taken place. From the negative of one photograph a positive is made, and this is superposed on the other negative so as to bring them into register, and the combination is viewed against a source of light. If the photographs have been made on similar plates and from nearly the same position with similar...
Apparatus. - The bulk of the paper is devoted to a careful description of the development of an apparatus for measuring the transmission of the atmosphere for light of different wave-lengths, of the methods of eliminating errors, of corrections to be applied, and of tests for the reliability of the results. Briefly, the method is to employ a modified Brace spectrophotometer near which is a source of light, a beam from which is reflected back to the spectra-photometer from a mirror distant 600...

Describes the results of experiments, made in the wind tunnel of the Bureau of Standards, on the air forces on a circular cylinder with its axis normal to the wind. A description of the wind-tunnel is given in the paper, and the results obtained are shown graphically. It is concluded that the wind-tunnel resistance equation R = ?AV/sup 2/f(VL/?) is not satisfied, but that the resistance coefficient R is a function of L, the diam. of the cylinder, as well as of VL/?, where ? = viscosity/?. The...
Apparatus. - This consists of a spectro-radiometer employing a wide receiver which permits of measuring a wide range of the spectrum, and hence the whole spectrum in a few steps. The instrument is mounted equatorially, and, by means of a planocylindrical quartz lens, the solar image is focused lengthwise directly on the slit. This means of focusing enables the instrument to be readily operated without clockwork. The solar image travels slowly along the slit, and a series of readings may be made...

Gives data on the reflecting power of monel metal, stellite, and zinc, in the visible spectrum and to 4 ? in the infra-red. In the infra-red the reflectivity of monel metal is practically the same as that of nickel; it varies from 57% at 0.45 ? to 91% at 4 ?. The values found for stellite confirm those previously obtained [see Abs. 1920A00343]. Zinc shows a deep depression in the reflectivity curve at about 1 ?, followed by an unusually high reflectivity beyond 2 ?. At 4 ? the reflecting power...
A description is given of a series of new observations on positive and negative spectrophotoelectric reactions in molybdenite, silver sulphide, and stibnite. With these new data are assembled and correlated the few previously observed photonegative reactions in selenium and stibnite. In view of the numerous variables involved, an attempt was made to determine the effect of each one upon the photoelectrical reaction, while other conditions were kept constant. It was found that the photopositive...

Describes a new form of vibration galvanometer, which consists of a fine steel wire mounted on one pole of a permanent magnet, and so arranged that the free end may vibrate between the poles of an electromagnet through which the current to be detected passes. The sensitivity, though less than that of instruments of the moving-coil type, is higher than that of other moving-iron instruments, while it possesses the qualities of sturdiness, quick responsiveness, and freedom from the effects of...

The work was carried out on a steel of the following percentage composition: C, 0.77; W, 17.8; Cr, 3.5; V, 0.74. The best magnetic results were obtained after quenching in oil, from 1050°C., when H/sub c/ = 70, B/sub rem./ = 6300, and B/sub max./ = 9100. By subsequent immersion in liquid air B/sub rem./ and B/sub max./ rose to 6700 and 9300 respectively. The Brinell and scleroscope hardness attained the max. value for steel quenched about 1070°C., and the highest density when quenched from...

Continuing, their systematic investigation of spectra in the red and infra-red regions [Abs. 1918A01160], the authors have made careful measurements of wave-lengths of lines in the spectra of titanium, vanadium, chromium, manganese, molybdenum, tungsten, and uranium. The concave-grating spectrograph of the Bureau of Standards was used to photograph the yellow, red, and infra-red arc spectra of these elements, the plates used being sensitised to the red and infra-red rays with pinacyanol and...

The ordinary hermetically sealed Clark cell is subject to two types of failure: the cracking of the glass near the amalgam, and the interruption of the circuit by the gradual formation of gas in the amalgam limb. The cracking of the glass has long been known to be due to the alloying of the amalgam with the Pt wire and a resultant increase in the diam. of the wire. The trouble may be largely overcome by employing platinum wire which has previously been subjected for a short time to the action...

Kennelly's law has been found to hold for pure homogeneous materials, except for points near the origin. Now, when the values of B/sub r/ and H/sub c/ are plotted against H/sub m/ the resulting curves have the same characteristics as the curve of B-H against H. There should hold, therefore, between these quantities a relationship similar to that expressed by the reluctivity law. Hysteresis measurements were made on a variety of materials ranging from Norway iron to KS steel, the apparatus...
